DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 369,102, dated August30, 1887.

Application filed January 21, 18s7. Serial No. 225,020. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM L. DAVIS, of South Amboy, in the county ofMiddlesex and State of New Jersey, have invented a new and ImprovedDumpingGar, of which the following is a full, clear, and exactdescription.

My invention relates to that class of dumping-cars ordinarily employedfor transporting coal, and which discharge their load through an openingin the bottom of the car-body closed by suitablycperating doors.

The object of the invention is to provide doors for regulating thedischarge-opening and mechanism for operating the doors, so constructedand arranged that the same can be easily opened to any desired extentand will be held in such adjustment, can be quickly and securely closedto cut off the discharge, and are not liable to become disarranged, andthat the operating mechanism will be wholly on the exterior of theload-bin, so as not to interfere with the free passage of coal, &c.,through the discharge-opening.

The invention consists in the construction, combination, and arrangementof parts, as hereinafter accurately described, and particularly pointedout in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of my improved dumping car, the dischargeopening being closed; Fig. 2 is a side elevation of the same. Fig. 3 isa longitudinal sectional view on the line 00 a: of Fig. 1. Fig. 4 is aninverted plan view of the car-body, showing: the dischargeregulatingdoors opened.

The car-body is adapted to be supported on trucks of the usualdescription, and the lower partsof the sides Aand ends B of the load-binconverge from the body-walls toward the discharge-chute O, which formsthe bottom of the bin.

The sides D of the chute O are vertical, and are supported by bottombeams, F, running lengthwise of the car-body .a short distance withinthe bottom side beams, G, of the same. The end walls, E, of the chuteconverge, the space between the lower ends of the same forming thedischarge opening. The discharge-opening is regulated by weighted doorsH, sliding on the under side of the inclined walls E of the chute,parallel with the same, in converging guides J, attached to the oppositevertical sides D of the chute and to the inner bottom beams, F, thesides D of the chute extending below the ends E of the same to carry thedoors and guides to a meeting and close the sides of the chuteautomatically. Chains K are attached to either end of each sliding doorH at the lower edge of the same, and are connected at their upper endsto transverse shafts L, journaled 'in suitable bearings in the innerbottom beams, F.

The ends of the shafts L at one side of the car-body project through thecorresponding inner beam, F, and are also journaled in bearings in theouter beam, G.

Chains M, attached to the shafts L between the beams F G, are wrappedaround the same in opposite directions, and are connected to a shortshaft, N, journaled in the beams F and G.

The short shaft N projects through the outer beam, G, and carries 'ahand-wheel, P, by turning which the chains M are wound on the shaft N,revolving the shafts L in opposite directions, and, through the mediumof the chains K, retracting the doors H.

For holding the doors open I provide a ratchet-wheel, Q, on theadjusting-shaft N, which wheel is engaged by a dog, R, pivoted to thecar-body. On releasing the dog R the doors descend by gravity to theirmeeting point and close the dischargeopening, the weight of thecontained load offering no obstruction to the closing, as is the casewith the usual drop-doors. 4

The door-operating mechanism being entirely without the load-bin, thecoal, &c., has a free passage in its discharge, and when frozen does nothinder the working of the doors.

In some cases I may use friction-rollers journaled to the sliding doorsor to their guides, to render the operation of the doors more easy andconvenient.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. In adumping-car, the combination, with theload-bin having a bottom discharge-opening, of a self-closingregulatingdoor therefor mounted to slide in an inclined plane, and meansfor raising and opening the said door, substantially as shown anddescribed.

2. In a dumping-car, the combination, with the load-bin having a bottomdischarge-opening, of regulating-doors therefor mounted to slide indownwardlyconverging planes, substantially as shown and described.

3. In a dumping-car, the combination, with the load-bin having a bottomdischarge-open ing, of a pair of regulating-doors therefor arrangedbelow the bin transversely of the car and movable lengthwise thereof, anadjusting shaft or shafts jonrnaled transversely of the car, and chainsconnecting said shaft or shafts with the doors, substantially as shownand described.

4. In a dumping-car, the combination, with the doors for regulating thedischarge-opening, of chains connected with each door, shafts on whichthe chains are wound, and meansfor revolving the shaftssimultaneously,said dooroperating mechanism being located outside of theload-bin, substantially as shown and described.

the load-bin, on which shafts the chains are wound, other chains, and anadjusting-shaft for revolving the horizontal shafts thereby,substantially as shown and described.

6. In a dumping-car, the combination, with the body having a load-bin,one wall of which is separated from the wall of the car-body, of 3 5 adoor or doors for regulating the dischargeopening in the load-bin,chains connected with the doors, winding-shafts journaled transverselybelow the load-bin, other chains, and

an adjustingshaft journaled transversely of 0 lVitnesses:
